Review: TP-Link Deco S4 (3-pack) – Finally killed every dead spot in my 4,800 sq ft house for under $130 - I live in a 1970s two-story brick house with plaster walls that eat WiFi for breakfast. My old ASUS router + extender setup left me with zero bars in the master bedroom, garage, and back patio. After fighting it for years, I grabbed this Deco S4 3-pack on a Prime Day deal for $119 and it’s been flawless for the last 14 months. Coverage & speed Placed one in the basement office, one on the main floor, one upstairs hallway Full bars everywhere now – even the detached garage 70 ft away pulls 180 Mbps down on 5 GHz Real-world speeds: 450-550 Mbps next to a node, 220-300 Mbps in the farthest corners (on a 500 Mbps fiber plan) Zero buffering on four 4K TVs streaming at once + two kids on Fortnite + my WFH Zoom calls Dead-simple setup Took 12 minutes total with the Deco app (literally plug in, scan QR code, done) Seamless roaming – phone/laptop walks from basement to backyard without dropping a single YouTube frame Guest network, parental controls, and QoS actually work and don’t require a PhD Reliability 14 months uptime, zero reboots needed Survived two 4-hour power outages (units just come back online when power returns) Runs cool and silent (no fans) Only two tiny gripes No dedicated backhaul band (it’s AC1900 tri-band in name only – shares 5 GHz for clients and backhaul), but with wired backhaul option or good node placement it’s never been an issue No USB port or fancy features, but I don’t care when it just works For $119-140 the 3-pack is stupid cheap compared to Eero or Nest (which I tried and returned). If you have a big house, thick walls, and just want rock-solid WiFi that you never have to think about again, buy these before the price goes back up. Already convinced three neighbors and my parents to ditch their old routers for the exact same kit. 10/10 – best money I’ve ever spent on networking. My WiFi problems are officially dead and buried.

## Questions & Answers

**Q: I have to-link  1750 with extender is this a better setup ?? Cause every once in awhile the extender loss singl.**
A: Extenders will definitely allow connections from further away, BUT they always cut your speed exactly in half. So an extender is just that a range extender, not a speed increaser, it decreases speed.  However the range extension can prevent dropouts so it acts like it is a speed increase but it is really just preventing dropouts (and remember it always cuts your speed in half).
On the other hand a Mesh system is actually 2 (or more) routers that you place in 2 different spots and so it does NOT start by cutting your speed in half. It is full speed. But since your computer (or wifi TV or doorbell etc) is closer to one of the 2 (or more) mesh spots it will also extend your range for that reason, and prevent dropouts for that reason. And the closer your device (computer, laptop, etc) is to the router, the chances are the faster the internet speed could very well be (for instance on the ookla online speed test website).

BUT an extender works with your old router. A mesh system IS a router (actually it is 2 or 3 or more routers), so it will not work with your old router. The routers are built in to the mesh system.  With an extender you need a router (your old one for instance), the extender(s), and a modem.

With a mesh system you just need the mesh system and a modem. You do not need a router (because it is built in).

**Q: how far from the base can a node be placed and does each node have to talk to the base or do they talk to one another in a chain?**
A: The nodes talk to each other to form the mesh network.  The setup app will guide you in the placement of each node.  My base is in one corner of the downstairs, I placed one node in the kitchen which is in the middle of the house and the other node upstairs.  That gave me great coverage everywhere in the house.

**Q: I just installed this and apple is indicating wpa/wpa2 (tkip) is not considered secure. how can i configure this to wpa2 (aes) or wpa3 security type?**
A: Hi! The security message you are receiving is due to a recent update of your smartphone’s mobile operating system. To remedy this message and to make sure your Deco S4’s encryption is optimally configured, please ensure your Deco app is fully updated, then update the firmware of your Deco S4. Once the firmware has been updated, the Deco S4’s WiFi encryption will be set to WPA2-PSK [AES] by default, so this message will no longer appear. 

For detailed instructions on how to update your Deco’s firmware, please visit FAQ 1599 on our official TP-Link website. To locate this FAQ, visit our website and enter 1599 in the top-right search field, then click the corresponding FAQ in the search results.

**Q: How reliable and user friendly are the parental controls?**
A: The Parental Controls feature on our Deco Mesh WiFi systems is designed to provide robust, yet intuitive and convenient features to help safeguard your network and those who use it. For more details on the Parental Controls feature, please visit FAQ 1598 on our official website.

### ⭐⭐⭐⭐⭐ Cheap, good, easy to setup.
*by C***E on June 3, 2026*

These things work so well for home use. I have four of these mesh routers in my house and garden. After the purchase, I had the problem that the routers needed to be reset from time to time, but TP-Link updated their app so that you can reset the routers automatically every night. Since then, they have been working 100% of the time. The internet is fast and reliable in every corner of my house. You can set up guest WiFi and many other things through the app on your phone. I can't think of an option or speed that you would need in a house setup. 100% recommended for the price!
